24AA024H-I/P

Memory IC Overview

The Microchip Technology 24AA024H-I/P is a 2 Kbit (256 x 8) serial electrically erasable PROM featuring a 2-wire I2C compatible interface. It operates on a single supply voltage ranging from 1.7V to 5.5V with a maximum clock frequency of 400 kHz. The device supports up to one million erase/write cycles and retains data for over 200 years. It includes hardware write protection for the upper half of the memory array via the WP pin, utilizes Schmitt trigger inputs for noise suppression, and is housed in an 8-pin PDIP package.

Memory IC Feature Summary

• Hardware write protection enables physical locking of the upper half of the memory array to prevent unauthorized or accidental data modification.
• Low-power CMOS technology ensures minimal active and standby current consumption, supporting extended battery life in portable applications.
• Schmitt trigger inputs combined with output slope control provide enhanced noise immunity and eliminate ground bounce during operation.

Memory IC Applications

• Industrial controllers requiring reliable non-volatile storage under noisy conditions
• Consumer electronics utilizing low-voltage power supplies
• Embedded systems needing hardware-level data security for critical parameters

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature range. Confirm the 'I' designation corresponds to the industrial temperature specification. Ensure compatibility with the system's I2C bus voltage levels before integration. Cross-reference the manufacturer part number against official datasheets to validate authenticity and revision status.

Memory IC Selection Notes

Select this component when a robust solution for small-scale non-volatile storage is required within industrial environments. The wide operating voltage range facilitates integration into systems powered by varying supply rails. The inclusion of a dedicated hardware write-protect pin offers a distinct advantage over software-only protection schemes for safety-critical data retention.

Memory IC Part Context

This device belongs to the 24AA024H/24LC024H family of 2Kb I2C Serial EEPROMs manufactured by Microchip Technology. The 'H' suffix indicates support for operation down to 1.7V, while the 'I' suffix denotes the industrial temperature grade. It serves as a standard memory solution for microcontroller-based designs requiring persistent data storage.

Memory IC Replacement Considerations

The 24LC024H-I/P is a functional equivalent within the same family, though it specifies a minimum operating voltage of 2.5V rather than 1.7V. Verify voltage requirements before substitution. Other capacity variants such as the 24AA08H or 24AA04H offer different memory sizes but share similar interface characteristics.
